Place the skeleton character performing a controlled bicep curl in a tight close-up frame, with small natural muscle definition and a semi-transparent skeleton overlay revealing realistic anatomy beneath the skin. The skeleton must stay consistent in 3D style with the selected reference. Use cinematic rim lighting with soft overhead contrast on a dark background, and shoot from a close front 3/4 camera angle. Add subtle haze and shadow falloff to enhance realism. Rendered in clean cinematic 3D, highly detailed.
